I’m Erin silva I’m an assistant professor in the uw Madison plant Pathology Department and the extension specialist in organic agriculture And I’m standing in front of our organic cover crop Base no-till plots So we have two different treatments here. This is our typical organic treatment So we’ve prepared the seed bed like we typically would with some Tillage and then planted the Soybean into clean ground and then went through with typical organic weed management Methods with ty we chose a drill cultivators and rotary hoes So you can see if it’s a nice Soybean stand, but we do have quite a few broadleaf weeds coming through here including pigweeds Ragweed and Giant Ragweed unfortunately in some other weeds that you typically would see in a Wisconsin organic production system Right here however. This is where we have the cover crop based no-till plot. So what we’ve done Here is plant a rye cover crop in September, so around September 15th We came through we drilled rye at about a rate of three bushels an acre and that Overwintered and started to grow again in April in may and when that cover crop reached and thisis at the end of may early June We rolled it with a roller crimper Ferns mounted on a tractor and then planted the Soybean directly behind that and you can see here There’s a thick mat of rye. That’s suppressing the weeds So once we planted this Soybean Unlike this plot here to the right of me the organic farmer didn’t have to do anything to this plot They were planted and there’s been no further weed management on this plot But you can see how incredibly clean it is and how incredibly well the Soybeans are doing they established incredibly well They’re they’re growing well, and we’re expecting to get a good yield off of this plot when we harvest in October And so this was funded by sare in 2009 some of the initial work where we compared different small grains that we could use as cover crops that could then be rolled And what we found out from that initial sare funded study Is that Riya is the superior cover crop for this system similar to what you’re seeing behind me we found that ryrylee? produces a very clean field with almost no weeds across the Soybean planting um However, we do see that the Soybeans do tend to Lag a bit behind that typical organic counterparts So what we’re doing on this field is Putting on different rates of composted poultry manure to see if we can use that as a starter fertilizer To try to make up for that initial lag and Soybean growth so we have two different rates of composted poultry manure or pelletized poultry manure that we put on here and We’ll measure yield at the end of the season to see if there is any benefit of that additional end at the beginning of the production season
